 Length 6-10 mm. = .24-.40 inch. Habitat. — Florida (Bay Biscayne) ; Cuba. 



[This species, taken in southern Florida by Mr. Schwarz, if not 

 originally native, seems to be successfully naturalized. The follow- 

 ing description is translated from that of Chevrolat 1. c. With the 

 insect in hand a better description is impracticable. 



"Brown, sericeous; head variejiated with yellow; thorax spinose each side, 

 transverse, with a double median line yellow, also two others at the sides and one 

 underneath on each side of the same color; elytra punctate at base, obliquely 

 truncate at apex, the outer angle acutely spinose, ornamented with three undu- 

 lated hands either yellow or white, one at base oblique, one at the middle and a 

 transverse one before apex; also a few dots of the same color; antenna^ with 

 joints 3-6 gray at base ; legs brownish ferruginous."] " Ham."

[This tribe is represented in our fauna by two genera which may 



be thuo separated : 



Thorax unarmed Aporataxia. 



Thorax armed Ataxia.
